I J i A further object' of this invention is to provide a'hoveI and improved purify ng mec anism d: eife'ctively purifying the solvent used in dry cleaning apparatus, said mechanism including a spray through which the dirty solvent is sprayed,

and including a plurality of super-imposed V screened basketsthrough which the solvent is forced to pass before reaching the discharge end of; the purifymg tank. I

. still further object of invention is t'o provide a purifying tank for use in a drylclea ning equipment, said tank 'comprisinga plurality l of supports, whereby a plurality of different mesh screens may be arranged within said tank, one above the other, and a spray disposed the upper end of'said tank adapted for spraying the dirtysolvent into said tank to force the same tdpass throughsaid screens before reaching the discharge end of" said tank.

A still further object of this invention isI to provide apurifying tank for dry cleaning" equipment, which will be economical to construct and assemble, which may be readily disassembled for examination or changing or cleaning of parts,

and which will be highly efficint for carrying out the purposes for which it is designed.

With the foregoing and other objects in v ew,

which will appear as the description proceeds, the

invention consists in certain novel features of construction, arrangement and combinationof parts, hereinafter more fully des'c'ribed,. i1lus trated in the accompanying drawing and par,-

ticularly pointed out in the appended el a'irm'it being understood that various changes the form, proportion, size and minor details ofthe structure may be made without departingffrom the spirit or sacrificing any of the advantagesof the invention. v

For the purpose of fai'zilitating an understand ing" of my invention, I have illustrated in the].

acc'drri a nying" agp're'ferrede embodiment a v thereof, froni-a spe no'f whic'h, whncon sideredin'cdn'neetidn withfth following descrip- The eonsii iciioiigjei dry; cleaning fapparatiis a plurality" of upstanding supports 23, the bot;

(01'. tit-134) Referring to'the drawing. iiif which siiiiiiai characters of reference arelemployed to indicate 5 corresponding arts throughout the several figures of the drawing': I ,V I. Figure 1 is a vertical section through a purifyin'g' tank embodying theflprinci'p'le's of my invention; and V r igizrez is a bottom plan view of the seating.

i'ii eii'i'is through which the dirtyfsolvent is'disj charged into the'purifyingtank; i .In the embodiment illustrated, ;the purifying tank comprises the out'en'shell 1Q,cwhic h may be constructed of anysiiitable material, said shell having the bottom end thereof, closed by the plate member 11, Which'plate' member is rigidly 5e ciired thereto in any suitable manner, such for eXarnpleas by means of the rivets 12 or theflike. The top of the'shell 10'is closed by a suitable cover member 13, by means of the locking meme there ,b' ipe. interposed a gasket 15b 1-;

7, fecdver member 13and the upper, ease of the shell 10. "A handle 16 is providedon the cover member 13 to facilitate the handling of the fsame. A-pet cook 17 is,.provided on the 13 and a pressure gauge 18 1s, t dj hr m yjm ans oiitki abe construction the shell; 10 is suitably sealed when in ope'rativecondition. i H

A clean out opening i9 is provided adjacent thelower end ofitheshellysaid opening being closed by a suitable member 20, held place by rrfeans of the bolts 21. In thebottom plate member 11 is provide an: outlet 22, through; received in the bottom of the. ischa'r ged toadesired point in b isedfor cleaning purposes.

p I "ed within the shell '10 are a plu'ral baske s dispose d fone above theothenfs'ai'd'ba ke'tsi being provided with suitable screened be I toms, and arranged" in a manner to' be now more. fu ly described' j j. Disposed oi; tiife'fb ttoi'i'i pla'tmii bi' .11 are tom edges, of which areben't inwardly'rto fllf l and the cf portions'ofalfd" I basket amprising an" annul example as by means of the rivets 27, to the inner upper portions of the upstanding members 23. Thebottom edge of the annular member 26 is bent inwardly as at 23, to form an annular inwardly extending flange, which is adapted to support in operative position the screens 29 and 30. In practice, the screen 29 is a 4-mesh screen of .047 galvanized iron, and the screen 30, .is an SO-mesh screen of Monel metal. Disposed adjacent the upper edge of the. annular member 26 are a plurality of angle bars 31, which are rigidly secured, such as by soldering'orth'e like, to the said member 26, said angle bars 31 forming a support for the basket 32 to be disposed thereon. The upper free edges of the supports 23 arealso provided with outwardly extending flanges 33, as shown in Figure 1 of the drawing.

The basket 32 is constructed in a manner similar to that of the basket 25, said basket 32 comprising an annular member 34, the bottom edge of which is bent inwardly to form the annular inwardly extending flange 35, which is adapted to rest on the supports 31, and which supports the screens 36 and 37 in their operative position. The screen 36 is similar in construction to the screen 29, and the screen 37 is a IO-mesh screen of Monel metal. Provided adjacent the upper free edge of the annular member 34 of the screen 32 are the inner and outer. anglebars 38, which are secured to the member 34 in any suitable manner, such as by soldering or the like, said members being provided for supporting the next adjacent basket disposed thereon.

This next basket 39 comprises the annular mem ber 40, the bottom edge of which is turned inwardly to form the annular inwardly extending flange 41, which rests upon the supports 38 and which is adapted to support in operative position the screen members 42 and 43. The screen member 42 is of similar construction to that of the screen member 29, whereas the screen member 43 is a GO-mesh screen of monel metal. Adjacent the upper edge of the annular member 40 are provided the supporting brackets 44 on both the inside and'outside of said member 40, which supporting brackets are adapted to support the next adjacent basket 45 disposed above the basket 39. f Y

As shown in Figure 1 of the drawing, the basket 45 comprises the annular member 46, the bottom edge of which is turned inwardly to form the annular inwardly extending flange 47 which rests upon the brackets 44, and which is adapted to support in operative position the screen member 48. In this basket the screen member is a 4-mesh screen of .047 galvanized iron. As shown in the drawing, the baskets 25, 32, 39 and 45 are disposed one upon the other and when in operative position the upper basket 45 is spaced from the upper edge of the shell 10.

In the space directly above the upper basket 45 is disposed a spraying unit 49, said unit being threaded on the elbow 50, which connects with a pipe 51, leading from the washer (not shown). Thedirty liquid from the washer enters the pipe 51 and is discharged through the elbow 50 into the member 49, which may be of any suitable shape,

such for example as that shown in Figure 1, and the bottom "end of said member 49 is closed by a spray head 52, which spray head is adapted for detachable engagement with the member 49 by means of the bayonet slot 53 provided therein and the pin 54 which cooperates with said bayonet slot.

As shown in the drawing, the member 49 terminates in its lower edge in a depending flange 55,

over which the spray head 52 is adapted to fit.

When in fully assembled position the spray 49 is disposed directly above the upper basket 45 so that the solvent issuing from said spray will drop into said basket.

To accomplish the clarifying and purifying of the fluid or solvent discharged from the spray 52, there is disposed a mass of cotton batting in the upper basket 45, and a quantity of calcium in the lower baskets 39, 32 and 25. The passage of the solvent through the'cotton batting and the three layers of calcium will be effective in clarifying the solvent, as well as taking out all of the moisture from the, solvent, the latter being accomplished by the solvent passing over the layers of calcium. The clear solvent will drop into the bottom end of the shell 10, from which it may be drawn up through the outlet 22 and directed to the desired point of the'dry cleaning system for reuse.

From the above it will be readily apparent that easy access may be had to the inside of the purifying tank by merely removing thecover member 13, at which time the spray head 49 may be readily removed from the elbow'5ofor cleaning the same. Also the provision of the bayonet slot connection between the spray head and the spray 52 will permit readily removal of the said spray 52 for cleaning out the same from timev to time. It will also be apparent that the disposition of the baskets one above the other will make it possible to readily remove the same whenever it is desired to change the contents thereof. In practice, however, it will only be necessary to change the cotton batting about once every'weekor ten days, which may be accomplished by merely removing the cover plate 13. The necessity for changing the calcium disposed in. the other baskets will not arise very frequently as the same may be used for a period of six months or longer with highly satisfactory results.

It is believed that my invention, its mode of construction and assembly, and many of its advantages should be readily understood and appreciated from the foregoing without further description, and should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes the structural details are, nevertheless, capable of wide variation. within the purview of my invention as defined in the appended claim.

What I claim and desire to secure by Letters Patent of the United Statesisr- A filter comprising a tank closed at its bottom andopen at its top, a removable closure member for the open top of said tank, a plurality of baskets disposed in said tank arranged one above the other, each of said baskets having a screened bottom and a solid annular wall, the bottom of said baskets being provided with legs secured thereto for supporting the same in spaced relation with the bottom Wall of the tank, means provided adjacent the free edge of each of said baskets for supporting thereon the next adjacent basket, said means including angular bars rigidly secured to the annular wall of the'basket to form inwardly extending projections upon which the next adjacent basket is adapted to rest, an inlet for said tank provided adjacent the upper end thereof and a spray connected with said inlet, said spray being disposed at a level below that of the upper free edge of the uppermost basket, whereby the liquid emitted through said spray will be received in said upper basket, cotton batting disposed within said upper one of said baskets, a moisture absorbing means disposed within the other of said baskets.
